Was ist denn das für ein FSK-Signal hier in JO43kb auf 10m? Ganz schön viel Hub.

It's back and this is how it looks like in closeup.

The FSK-like appearance must have been aliasing between the FFT rate of my UberSDR and the scan rate of the OTHR.

@hennichodernich Ich verwende Thetis 2.10.3.13 mit ANAN-G2.

@hennichodernich FMCW mit 50 Hz SPS, von PRF kann man hier nicht sprechen, da quasi continuous wave. Mit Inspectrum NG von HydraSDR (github) kann man sich iq files sehr schön ansehen.

@hennichodernich if it's what I think it is, if you speed up the vertical scroll rate you should be able to discern four distinct frequencies, in pairs, opposite to each other.

@vk6flab Didn't find that setting in UberSDR yet. And don't know if that's configurable since the DSP is done by ka9q-radio.
